Boot device: disk File and args:
SIProgram terminated
{0} ok

After checking out gentoo on sparc forum ,I follow some advise to fix this peoblem.Finanlly.the box became bootable with reruning silo programe.
But I can't fing the reason which case the machine can't autoboot with command boot sometimes.
